The quick mount adapter serves as a connector on the tripod or pole between the threaded joint and the surveying equipment being mounted.
FIG. 1 illustrates a general view of a quick mount adapter 100 according to an embodiment of the present invention. The quick mount adapter 100 is used to mount and fix a mountable device, such as geodetic/surveying equipment, onto a support apparatus, such as a tripod or a pole, with an external guided screw. As used herein, the term “mountable device” refers to any device, instrument, or equipment that can be mounted on a support apparatus, such as a tripod or pole, via a threaded joint. In accordance with various embodiments, the mountable device mounted using the quick mount adapter 100 may be a geodetic/surveying instrument, such as a theodolite, total station, automatic level, Global Navigation Satellite System (GNSS) receiver, GNSS antenna, laser level, digital level, geodetic reflector, Millimeter (MM) Global Positioning System (GPS) Transmitter and Sensor, or other surveying accessory equipment, but the present invention is not limited thereto. In other embodiments, the quick mount adapter 100 may be used to mount other types of devices, such as cameras, video cameras, various optical equipment or lighting equipment, etc., to a support apparatus. As used herein, the term “support apparatus” refers to any tripod, pole, or stand to which a mountable device can be mounted via a threaded joint.
The quick mount adapter 100 serves as a connector between the threaded screw on the support apparatus and the mountable device. The quick mount adapter 100 frees the user from the need of screwing a mountable device onto the external threaded screw of the support apparatus, thereby facilitating and speeding up the installation of the mountable device onto the support apparatus and the subsequent removal of the mountable device from the support apparatus. As shown in FIG. 1, the quick mount adapter includes a main body 101, a rotatable cylinder 110, a collet clamp 120, a locking cover 130, and a catcher 140. The main body 101 of the quick mount adapter 100 has an internal threaded groove that is screwed onto the external threaded screw of the support apparatus in order to fasten the quick mount adapter 100 to the support apparatus. The size of the threading of the quick mount adapter is selected to ensure compatibility with the support apparatus and the mountable devices that can be mounted to the support apparatus. In an advantageous embodiment, the quick mount adapter may have ⅝-11 UNC internal threading to in order to attach to support apparatus having a ⅝-11 UNC threaded screw. The top portion of the catcher 140 is sized to engage with and fit within a socket of the mountable device. In an advantageous embodiment, the diameter of the top portion of the catcher 140 can be smaller than a ⅝-11 UNC thread in order to fit within a 5 8/11 UNC threaded socket of the mountable device without being screwed in. A top surface of the locking cover 130 can be formed with bosses 134, which engage with slots on the mountable device in order to prevent the mountable device from rotating about a vertical axis when the mountable device is mounted to the support apparatus using the quick mount adapter 100.
FIG. 2 illustrates a detailed view of the structure of the quick mount adapter 100 according to an embodiment of the present invention. As shown in FIG. 2, the main body 101 of the quick mount adapter 100 includes a base portion 102 and upper portion 103 extending from the base portion 102. The upper portion 103 of the main body 101 has a smaller diameter than the base portion 102, which allows the rotatable cylinder 110 to be installed on the upper portion 103 and sit flush with the base portion 102. The main body 101 is hollow and has internal threading which allows the main body 101 of the quick mount adapter 100 to fasten onto the threaded screw of the support apparatus. For example, the internal threading of the main body may be ⅝-11 UNC, but the present invention is not limited thereto. The upper portion 103 of the main body 101 has a central lead opening 104 that accommodates the collet clamp 120, side openings 105 for lead screws 108, and threaded holes 106 for fixing the locking cover 130 to the main body 101.
The rotatable cylinder 110 is disposed over the upper portion 103 of the main body 100, such that the upper portion 103 is inside of the rotatable cylinder 110, and sits on top of the base portion 102 of the main body 101. The outer diameter of the rotatable cylinder 110 may be equal to the diameter of the base portion 102 of the main body 101, such that the outer surface of the rotatable cylinder 110 is flush with the outer surface of the base portion 102 of the main body 101. The length of the rotatable cylinder 110 may be equal to the length of the upper portion 103 of the main body 101. The rotatable cylinder 110 is rotatable with respect to the upper portion 103 of the main body 100. In an advantageous embodiment, the rotatable cylinder 110 is made of an antifriction material (i.e., a material with a low coefficient of friction). For example, the rotatable cylinder 110 can be made of nylon or polytetrafluoroethylene (PTFE), but the present invention is not limited thereto. Alternatively, the rotatable cylinder 100 can be coated with an antifriction coating, or a lubricant can be used to reduce friction between the inner surface of the rotatable cylinder 110 and the outer surface of the upper portion 103 of the main body 101. The rotatable cylinder 110 includes two bayonet slots 111 to transfer rotational movement of the rotatable cylinder 110 into translational movement via the lead screws 108.
The collet clamp 120 includes a plurality of collets 121, each with a thickened portion 122 at the end. The collets 121 are spring leaves that surround and grip a shaft of the catcher 140. In the embodiment of FIGS. 1 and 2, the collet clamp 120 includes four collets 121 (spring leaves), but the present invention is not limited thereto and more or less collets/spring leaves may be used. In an exemplary implementation, the collets 121 may be made of spring steel. The collets 121 extend from a bottom portion 123 of the collet clamp 120 which is accommodated in the central lead opening 104 of the main body 101. The bottom portion 123 of the collet clamp 120 has threaded holes 124 for the lead screws 108. The collet clamp 120 is moveable in a vertical direction within the upper portion 103 of the main body 101. The collet clamp 120 together with the catcher 140, and as the collet clamp 120 moves downwards (i.e., towards the base portion 102), the catcher 140 opens the collets 121 causing the thickened portions 122 of the collets 121 to hold the mountable device on the quick mount adapter 100.
The lead screws 108 are fixed in the threaded holes 124 of the collet clamp 120 and transfer rotational motion of the rotatable cylinder 110 into translational movement of the collet clamp 120. Outer portions of the lead screws pass through the side openings 105 of the upper portion 103 of the main body 101 and are accommodated in the bayonet slots 111 of the rotatable cylinder 110. The side openings 105 in the main body 101 permit the lead screws 108 to move with the collet clamp 120 in a vertical direction with respect to the upper portion 103 of the main body 101 (i.e., toward or away from the base portion 102). The bayonet slots 111 of the rotatable cylinder 110 are sloped such that when the rotatable cylinder 110 is rotated in a first direction (e.g., clockwise), the bayonet slots 111 force the lead screws 108 accommodated therein to move downward (i.e., toward the base portion 102) within the side openings 105 of the main body 101. Since the lead screws 108 are fixed in the collet clamp 120, the downward movement of the lead screws 108 causes the collet clamp 120 to move downward within the upper portion 103 of the main body 101.
The locking cover 130 fixes the catcher 140 in place and prevents axial movement of the rotatable cylinder 110. The locking cover 130 includes screw holes 131 that are aligned with the threaded holes 106 on the upper surface of the main body 101. The locking cover 130 is disposed above the rotatable cylinder 110, and the locking cover 130 is attached to the main body 101 using screws 136 that are threaded through the screw holes 131 of the locking cover 130 into the corresponding threaded holes 106 of the main body 101. For example, the screws 136 may be M2 screws, but the present invention is not limited thereto. In the embodiment of FIGS. 1 and 2, five screws 136 are used to connect the locking cover 130 to the main body 101, but the present invention is not limited thereto and the number of screws 136, screw holes 131, and threaded holes 106 may vary. The diameter of the locking cover 130 may be equal to the diameter of the rotatable cylinder 110 and the diameter of the base portion 102 of the main body 101. The locking cover 130 includes a center threaded hole 132 in which a threaded portion of the catcher 140 is fixed, and collet slots 133 surrounding the center threaded hole 132. The collets 121 of the collet clamp 120 pass through the collet slots 133 of the locking cover 130 to surround and grip a shaft of the catcher 140. The number of collet slots 133 corresponds to the number of collets 121 of the collet clamp 120. In the embodiment of FIGS. 1 and 2, there are four collet slots 133 corresponding to the four collets 121 of the collet clamp 120. The locking cover 130 includes a plurality of bosses 134. In an advantageous embodiment, a bottom surface of the mountable device or a special insert installed within the mountable device can be formed with slots corresponding to the bosses 134. The bosses 134 are raised portions protruding from an upper surface of the locking cover 130 that engage with the slots on the bottom surface of the mountable device or special insert to prevent the mountable device from rotating when mounted on the quick mount adapter 100. In the embodiment of FIGS. 1 and 2, the locking cover 130 has three bosses 134, but the present invention is not limited thereto and more or less bosses may be used.
The catcher 140 includes a threaded portion 141, a shaft having a narrow part 142 and a wide part 143, and a head 144. The catcher 140 is installed on the locking cover using a threaded joint, by fixing the threaded portion 141 of the catcher 140 into the center threaded hole 132 of the locking cover 130. The shaft of the catcher 140 is between the threaded portion 141 and the head 144. The narrow part 142 is the upper portion of the shaft (adjacent to the head 144) and the wide part 143 is the lower portion of the shaft (adjacent to the threaded portion 141). The wide part 143 of the shaft has a greater diameter than the narrow part 142 of the shaft. The collets 121 of the collet clamp 120 surround and grip the shaft of the catcher 140, and when the collet clamp 120 moves downward, the collets 121 move from the narrow part 142 to the wide part 143 of the shaft, and the wide part 143 causes the collets 121 to be opened outward. When the collets 121 are forced to open due to the wide part 143 of the shaft of the catcher 140, the thickened portions 122 at the ends of the collets 121 grip an inner portion of the socket of a mountable device, thus locking the mountable device onto the quick mount adapter 100. The head 144 of the catcher 140 is sized to fit within the socket of the mountable device. In an advantageous embodiment, the head 144 of the catcher 140 can be smaller than a ⅝-11 UNC thread in order to fit within a 5 8/11 UNC threaded socket of the mountable device without being screwed in.
FIG. 3 illustrates dimensions of the quick mount adapter 100 in an exemplary embodiment. In particular, FIG. 3 shows the dimensions for the quick mount adapter 100 in an advantageous embodiment in which the quick mount adapter 100 is used with a ⅝-11 UNC threaded joint. In the embodiment of the FIG. 3, the overall length of the quick mount adapter 100 from the bottom of the base portion 102 of the main body to the head 144 of the catcher 140 is 119 mm. The length from the bottom of the main body 101 to the top surface of the locking cover 130 is 100 mm. The diameter of the base portion 102 of the main body 101, the rotatable cylinder 110, and the locking cover 130 is 35 mm, and the diameter of the head 144 of the catcher 140 is 13.60 mm.
FIGS. 4 and 5 illustrate the operation of the quick mount adapter 100 to mount a mountable device according to an embodiment of the present invention. FIG. 4 illustrates a starting position of the quick mount adapter 100. FIG. 5 illustrates a fixed position of the quick mount adapter 100 in which a mountable device is mounted on the quick mount adapter 100. As shown in FIG. 4, at the starting position, the rotatable cylinder 110 is turned counterclockwise as far as permitted by the lead screws 108 accommodated in the bayonet slots 111. The collet clamp 120 is at its top position, and the collets 121 are in an undisturbed state.
In order to mount a mountable device, such as a surveying device, onto the quick mount adapter 100, the mountable device is placed on the quick mount adapter 100 at the starting position. According to an advantageous embodiment mountable, the mountable device is provided with a special insert 302. The special insert 302 has an external thread for installing into a threaded socket of the mountable device and an inner thread forming a threaded socket for mounting the mountable device to a support apparatus. One feature of the special insert 302 is in addition to thread, an inner portion of the special insert 302 has a groove 303 designed to engage with the collets 121 of the collet clamp 120 of the quick mount adapter 100. The mountable device is placed on the quick mount adapter such that the head 144 of the catcher 140 is inside a socket of the special insert 302 installed within the mountable device. The bottom surface of the mountable device and/or the special insert 302 rests on the upper surface of the locking cover 130 and the bosses 134 on the locking cover 130 engage with slots in the bottom surface of the special insert or mountable device. As shown in FIG. 5, once the mountable device is placed on the quick mount adapter 100, the rotatable cylinder 110 is rotated clockwise around the upper portion 103 of the main body 101. The bayonet slots 111 cause the lead screws 108 to move downward with respect to the upper portion 103 of the main body 101 when the rotatable cylinder is rotated clockwise, and the downward movement of the lead screws 108 causes the collet clamp 120 is move downward within the upper portion 103 of the main body 101. As the collet clamp 120 moves downward, the collets 121 slide along the shaft of the catcher 140 and move from the narrow part 142 to the wide part 143 of the shaft. The collets 121 are forced open by the wide part 143 of the catcher 140, which causes the thickened ends 122 of the collets 121 to engage with the groove 303 on the inner portion of the socket of the special insert 302, thereby holding the special insert 302 and the mountable device in the fixed position on the quick mount adapter 100.
Once a mountable device is mounted on the quick mount adapter, the mountable device is removed by implementing the steps of the mounting process in the reverse order. In particular, starting with the quick mount adapter 100 in the fixed position (FIG. 5) with a mountable device mounted on the quick mount adapter 100, the rotatable cylinder 110 is rotated counterclockwise to return the quick mount adapter to the starting position (FIG. 4). The bayonet slots 111 cause the lead screws 108 to move upward when the rotatable cylinder 110 is rotated counterclockwise, which forces the collet clamp 120 to move upward and the collets 121 to slide along the shaft of the catcher from the wide part 143 to the narrow part 142 and close inward. This causes the thickened end portions 122 of the collets 121 to disengage with the inner portion of the socket 302 of the mountable device. Once, the quick mount adapter 100 is returned to the starting position and the thickened end portions 122 of the collets no longer engage with the inner portion of the socket 302, the mountable device can be removed from the quick mount adapter 100. As described herein, in an advantageous embodiment, the rotatable cylinder 110 is rotated clockwise to put the quick mount adapter 100 in the fixed position and counterclockwise to return the quick mount adapter 100 to the starting position. It is to be understood that in other embodiments, these rotation directions may be reversed by sloping the bayonet slots 111 in the opposite direction.
FIG. 6 illustrates a mountable device mounted to a support apparatus using the quick mount adapter according to an embodiment of the present invention. As illustrated in FIG. 6, the support apparatus is a tribrach 200 and the mountable device is a GNSS receiver 300. As is well known, a tribrach 200 is an attachment plate used to attach a surveying instrument, such as a theodolite, total station, GNSS antenna, etc., to a tripod. The tribrach 200 includes a rotating tribrach adapter 201 and an external guided screw 202 extending from the rotating tribrach adapter 201. For example, the external guided screw 202 may be a ⅝-11 UNC screw, but the present invention is not limited thereto. The quick mount adapter 100 is fixed to the tribrach 200 via a threaded joint by screwing the external guided screw 202 of the tribrach 200 into the internal threading of the main body 101 of the quick mount adapter 100. According to an advantageous embodiment, the GNSS receiver 300 is provided with a special insert 302. The special insert 302 has an external thread for installing into a threaded socket of the mountable device and an inner thread forming a threaded socket for mounting the GNSS receiver 300 to a support apparatus. For example, the special insert 302 may be a ⅝-11 UNC threaded socket, but the present invention is not limited thereto. In addition to thread, an inner portion of the special insert 302 has a groove 303 designed to engage with the collets 121 of the collet clamp 120 of the quick mount adapter 100. A bottom portion of the special insert 302 or the mountable device (e.g., GNSS receiver 300) can include a plurality of slots to engage with the plurality of bosses 134 on the locking cover 130 of the quick mount adapter 100. The GNSS receiver 300 is mounted on the quick mount adapter 100 by placing the socket of the special insert 302 on the head 144 of the catcher 140 of the quick mount adapter 100 and rotating the rotatable cylinder 110 of the quick mount adapter 100 to put the quick mount adapter 100 in the fixed position, as described above in connection with FIGS. 4 and 5. The GNSS receiver 300 is dismounted from the quick mount adapter by rotating the rotatable cylinder 110 of the quick mount adapter 100 to return the quick mount adapter 100 to the starting position, as described above in connection with FIGS. 4 and 5, and then removing the GNSS receiver 300 from the quick mount adapter 100. Since the quick mount adapter 100 is fixed onto the tribrach 200, the GNSS receiver 300 can be mounted on the tribrach 200 and removed from the tribrach 200 quickly and easily using the quick mount adapter 100, without having to screw/unscrew the external guided screw 202 of the tribrach 200 into or out of a socket of the surveying device 300.
In the embodiments described above, the quick mount adapter 100 connects a support apparatus having an external threaded screw of a certain size (e.g., ⅝-11 UNC) with a mountable device having a compatible sized socket. In another possible embodiment, the quick mount adapter 100 can also be used to connect a support apparatus with a certain size threaded screw with a mountable device having a different sized socket. In this case, the internal threading of the main body 101 can be sized to be threaded onto a first sized external threaded screw and the head 144 of the catcher can be sized to fit within a second sized socket.
